• CPU frequancy stuck at 1.20 GHz using TLP?

  - by Rana Muhammad Waqas

  I have installed TLP for power optimization on Ubuntu 13.10. Instructions I start computer its running fine I can change the CPU frequencies to whatever I want, but after some time it stuck on minimum frequency 1.20 GHz, I cant change that to anything else. I have tried to stop it by using sudo tlp stop but it doesn't stop. Tried even to kill its process sudo killall tlp but it seems they have a different name of process of that so i am not sure what to do now. I reported to the linrunner but cant seem to find a solution

• Recommendation for Improving Programming Skills

  - by Moaz ELdeen

  I'm 25, I know C++ syntax since 9 years.. but It seems that I have copied so much code, and I didn't learn that much and didn't solve a lot of algorithms in my own. Currently I'm working for computer vision programmer as a junior and I have difficulity of doing algorithms like blob tracking or object tracking, writing algorithms like KNN, Quadtree,..etc. I don't know what to do, or what to improve, I tried to write asteriods game, I have finished it, and here you can watch it https://www.youtube.com/watch?v=jw0L4aCB4TU What should I do more to enhance my skills ?

• Using shortkeys to search the internet for a term selected in a text editor/viewer

  - by cipricus

  It seems possible (as I learned from a comment to this question made by user55822) to use a command in order to search a term on the web by using "keybinding" the way Aretha is used. What the aforementioned user says is that "you could search mouse selection anywhere by using an app like Artha, or by keybinding sh -c 'firefox "http://translate.google.com/#en/fr/$(xclip -o)"' (example given translate english into french)" A lot of things are obscure for me here. I could use Artha or keybinding (as alternative), or both? How to do that in each case? and "The command I gave you will open google translate in Firefox with your mouse selection (text highlighted) as a query. Use sh -c 'firefox "https://www.google.com/search?q=$(xclip -o)"' if you want regular Google over Google translate. And obviously, that would work everywhere" I do not know what to do with that formula. What should I do exactly? How to use it? In what application?

• Software/Hardware Development?

  - by SwarthyMantooth

  Sincere apologies if this is the wrong place to ask this. I am a computer engineering student and I'm currently on my first co-op of the required 5 I have to take, and I've noticed that all I'm really given is software engineering jobs. I love developing software, but I don't want to lose out on the hardware aspect of computers, as having a hybrid knowledge of the two is why I chose this major in the first place. So I guess my question is: Are there any software engineering jobs that still allow you to handle and interface with hardware on a very low level? Or am I to be forced to choose which focus I love more?

• What triggered the popularity of lambda functions in modern programming languages?

  - by Giorgio

  In the last few years anonymous functions (AKA lambda functions) have become a very popular language construct and almost every major / mainstream programming language has introduced them or is planned to introduce them in an upcoming revision of the standard. Yet, anonymous functions are a very old and very well-known concept in Mathematics and Computer Science (invented by the mathematician Alonzo Church around 1936, and used by the Lisp programming language since 1958, see e.g. here). So why didn't today's mainstream programming languages (many of which originated 15 to 20 years ago) support lambda functions from the very beginning and only introduced them later? And what triggered the massive adoption of anonymous functions in the last few years? Is there some specific event, new requirement or programming technique that started this phenomenon?

• Named arguments (parameters) as a readability aid

  - by Damian Mehers

  A long time ago I programmed a lot in ADA, and it was normal to name arguments when invoking a function - SomeObject.DoSomething(SomeParameterName = someValue); Now that C# supports named arguments, I'm thinking about reverting to this habit in situations where it might not be obvious what an argument means. You might argue that it should always be obvious what an argument means, but if you have a boolean argument, and callers are passing in "true" or "false" then qualifying the value with the name makes the call site more readable. contentFetcher.DownloadNote(note, manual : true); I guess I could create Enums instead of using true or false (Manual, Automatic in this case). What do you think about occasionally using named arguments to make code easier to read?

• The provider did not return a ProviderManifestToken string Entity Framework

  - by PearlFactory

  Moved from Home to work and went to fire up my project and after long pause "The provider did not return a ProviderManifestToken string" or even More Abscure ProviderIncompatable Exception Now after 20 mins of chasing my tail re different ver of EntityFramework 4.1 vs 4.2...blahblahblah Look inside at the inner exception A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible DOH!!!! Or a clean translation is that it cant find SQL or is offline or not running. SO check the power is on/Service running or as in my case Edit web.config & change back to Work SQL box   Hope you dont have this pain as the default errors @ the moment suck balls in the EntityFramework 4.XX releases   Cheers

• Cisco AnyConnect VPN Client broke my internet

  - by user137864

  I was using the AnyConnect client when it froze and I had to do a hard reboot of my computer. Now I can't connect to the internet at all, with or without VPN. The Network Connections manager seems to think I have a wired and wireless connection without a problem, but I can't go online. I have tried using /etc/init.d/networking restart and it even says it is "ok" with no luck. I am guessing I need to clear some settings somewhere and restart a service, but I am not sure what. Thanks!

• How to use short breaks at work effectively for self-development?

  - by Alaudo

  At the moment my daily work as a developer requires me to have short 10-20 min breaks after every 2-3 hours. It would be nice if I could use those effectively to improve my expertise in programming or CS in general. I tried several things: Reading jokes online gets boring very soon. Trying to solve some (even the most simple) tasks from different code contests requires more time, as long as I have some idea of an algorithm the time is over. Reading a randomly picked Wikipedia-article about Computer Science: depending upon the article sometimes it requires more time and is not an easy reading for a break. So, I ended up reading StackOverflow questions and answers with most votes: that is entertaining and educative. Do you have any other suggestions?

• Is conditional return type ever a good idea?

  - by qegal

  So I have a method that's something like this: -(BOOL)isSingleValueRecord And another method like this: -(Type)typeOfSingleValueRecord And it occurred to me that I could combine them into something like this: -(id)isSingleValueRecord And have the implementation be something like this: -(id)isSingleValueRecord { //If it is single value if(self.recordValue = 0) { //Do some stuff to determine type, then return it return typeOfSingleValueRecord; } //If its not single value else { //Return "NO" return [NSNumber numberWithBool:NO]; } } So combining the two methods makes it more efficient but makes the readability go down. In my gut, I feel like I should go with the two-method version, but is that really right? Is there any case that I should go with the combined version?

• RPi and Java Embedded GPIO: Connecting LEDs

  - by hinkmond

  Next, we need some low-level peripherals to connect to the Raspberry Pi GPIO header. So, we'll do what's called a "Fry's Run" in Silicon Valley, which means we go shop at the local Fry's Electronics store for parts. In this case, we'll need some breadboard jumper wires (blue wires in photo), some LEDs, and some resistors (for the RPi GPIO, 150 ohms - 300 ohms would work for the 3.3V output of the GPIO ports). And, if you want to do other projects, you might as well by a breadboard, which is a development board with lots of holes in it. Ask a Fry's clerk for help. Or, better yet, ask the customer standing next to you in the electronics components aisle for help. (Might be faster) So, go to your local hobby electronics store, or go to Fry's if you have one close by, and come back here to the next blog post to see how to hook these parts up. Hinkmond

• have a missing file, and cant run ubuntu upon start up, and hasnt the flash drive i used didnt work either, any help?

  - by trent

  when I first downloaded Ubuntu to install it, it downloaded quick and caused no problems to my laptop. but then when it came time to install it as one of my operating systems, it wouldn't run because it said a file was missing or damaged. so then I uninstalled it and re-installed it but I still had that same problem. so I tried a flash-drive version but that didn't work either because it wouldn't boot from that, nor would it detect my flash drive, (in this case, an old 4 GB mp3 player). any help or tips and ideas would be great, I just need a decent operating system because windows is getting to be terrible at the moment, just note I wanna run Ubuntu along side windows 8.1

• Is nesting types considered bad practice?

  - by Rob Z

  As noted by the title, is nesting types (e.g. enumerated types or structures in a class) considered bad practice or not? When you run Code Analysis in Visual Studio it returns the following message which implies it is: Warning 34 CA1034 : Microsoft.Design : Do not nest type 'ClassName.StructueName'. Alternatively, change its accessibility so that it is not externally visible. However, when I follow the recommendation of the Code Analysis I find that there tend to be a lot of structures and enumerated types floating around in the application that might only apply to a single class or would only be used with that class. As such, would it be appropriate to nest the type sin that case, or is there a better way of doing it?

• Inspecting the model in a Rails application

  - by Matt Sherman

  I am learning some Ruby on Rails, and am a newbie. Most of my background is in ASP.net MVC on the back end. As I play with a basic scaffold project, I wonder about this case: you jump into an established Rails project and want to get to know the model. Based on what I have seen so far (again, simple scaffold), the properties for a given class are not immediately revealed. I don't see property accessors on the model classes. I do understand that this is because of the dynamic nature of Ruby and such things are not necessary or even perhaps desirable. Convention over code, I get that. (Am familiar with dynamic concepts, mostly via JS.) But if I am somewhere off in a view, and want to quickly know whether the (eg) Person object has a MiddleName property, how would I find that out? I don't have to go into the migrations, do I?

• Masters for Artificial Intelligence

  - by Frenchie

  I am very interested in going to graduate school to study Artificial Intelligence. I am currently an undergrad student majoring in Computer Science, I will be finished in a year and a half so I figured now is a good time to start looking. I do not have a competitive GPA(3.3) so I am not looking for the top 25 graduate schools in AI such as listed in this ranking. So far I am taking into consideration the University of Georgia, they have a masters in AI, separate from a masters in CS. If you know of any other schools that has a decent masters in CS with an emphasis on AI or a masters in AI by itself please let me know. Thank you. USA/Canada schools only.

• Slow wifi with D-link DWA-160 A2

  - by Tommy Brunn

  I recently bought a USB wifi adapter for my new desktop computer. It's a D-link DWA-160 A2. From the start it didn't want to work at all, but after unplugging and then plugging it back in, it seems to work. However, my browsing is painfully slow. NetworkManager reports the connection to be at around 78-85% signal strength, which seems perfectly acceptable. Is there anything I can do to make it faster? I'm dual booting with Windows 7, where it seems to work fine, so I'm guessing that the problem occurs because of crappy drivers.

• What will be a good python script (or your favorite language goes here) to test a system's performance and capabilities?

  - by dassouki

  Let's say you're in a computer store looking at 10 laptops, you want to really compare the system's capabilities. What will be an efficient "your fav language goes here" script that will allow you to do this? As an example, when I go to the store I usually open a macbook and a pro's terminal and write an equation in python, iterate it a million or so times, and time them. I like to compare the difference in time. What would be an ideal and simple script that can efficiently compare systems?

• All video players display black screen.

  - by Dennis

  I'm working in 10.04 Lucid. All my video players (Movie Player and VLC) and the preview windows in editors (OpenShot and Pitivi) will only display a black screen when playing a video. The sound is fine and the videos work fine on other computers. I have tried multiple formats from varying sources .MOV taken from old ffmpeg projects, .AVI straight from a camera, .MP4 using h.264 from OpenShot on another system, .OGV from a gtk-recordmydesktop session on this very computer. I even get a pure black screen in the viewer when starting a remote session in VNC. This box has a GeForce 8400 GS using the Nvidia drivers in case it may be a card problem or setting.

• How to get useful feedback/bug reports from users

  - by Mikael Eliasson

  I'm sure most webmasters have recived a mail like this: Creating [insert item here] is not working! When you check it out there is no general problem with the function but rather the user has discovered an edge case. Almost every mail I get is like this and in the long run it gets a bit annoying to always have to ask the user for more information. Is there anything I can do to get my users provide more useful feedback? Right now I have a mailto: for the webmaster mail in the page footer. I was thinking of changing this so that they have to report through a form on the site. Anyone got any experience with this? Do you get better/more reports by having a feedback form instead of giving the users the email?

• Developing Browser plugins. Spcially for chrome and firefox, what is the future?

  - by MobileDev123

  I am interested to learn developing some plug ins for chrome and Firefox browsers as hobby projects. However I know nothing about it, and I don't know if it is valuable for professional experience or not. Do you know anybody who's developing this kind of plug ins professionally? In case I can develop any plug in, does it have any significance in my resume? (Extra info: I have 1.5 years of experience in various Java Techs, from servers to mobile). How some companies and some other employers can see this plug in development professionally?

• Is it worth it to learn some programming before college?

  - by Howlgram

  I'm in my last year of highschool and I am very interested in programming, the thing is I don't know if it could be worth it to start learning programming now, im afraid that when I get to college they might just teach all I might have learned in a few classes making a waste the time spent on learning that before college. Right now I'm on my last year of highschool and I know absolutely nothing about programming. There are other similar questions where people answer saying it is good to learn beforehand, but I doubt their situation might be like mine, maybe they had much more time to learn programming (as if they were not on their last year of highschool) before college so they could learn some serious skills, besides they say they already know at least the basics about a language, instead, I know nothing and I have no idea how much could I learn this year. If it wasn't clear I want to study computer's science

So is there any way to get out of this problem, neithet I can open xp nor linux?

• Why is nesting or piggybacking errors within errors bad in general?

  - by dietbuddha

  Why is nesting or piggybacking errors within errors bad in general? To me it seems bad intuitively, but I'm suspicious in that I cannot adequately articulate why it is bad. This may be because it is not in general bad and that it is only bad in specific instances. Why is it detrimental to design error/exception handling in such a way. The specific instance is that of a REST service. There is a desire by some to use http errors (specifically the 500 response) as a way to indicate any problem with specific instances of a resource. An example of an instance resource in this case would be: http://server/ticket/80 # instance http://server/ticket # not an instance So this is the behavior that is being proposed. If ticket 80 does not exist return a http response code of 500. Within the body of the error return the "real" error as an additional error code and description. If the ticket resource doesn't exist return a response code of 404.

• What features of old computers helped you learn to be a better programmer?

  - by David Cary

  What features of old computers helped you learn to be a better programmer -- but don't seem to be available on new computers? I imagine that, while educational, you are really glad some features are gone, such as programs ran so slowly that I could almost see each pixel being plotted, so I got a visceral feel for the effect of various optimizations. I imagine other features you may be a little nostalgic for, such as I could turn on the computer, and write a short program that printed "Hello, World" on the printer, before ever "booting" a "disk". (I'm hoping that this is constructive enough to avoid the fate of the " What have we lost from computers 20 years ago ?" question).
